In 1969 Mrs Doris V Allen, the widow of the Rev Dr Robert Allen who was Honorary Secretary of the Presbyterian Historical Society for many years made a donation to the Society to create The Robert Allen Memorial Lecture, an annual lecture dealing with some aspect of Irish Ecclesiastical History.
The inaugural lecture was held in Union Theological College in March 1971.
A lecture has been delivered every year except for 1972, 1983 and 1986.
The full list of the Lectures has been compiled and is now available on The Robert Allen Memorial Lecture page.
